INSTALLATION
AND
OPERATION MANUAL
Z-600 Six Zone Comfort System™
READ THIS MANUAL THOROUGHLY BEFORE PROCEEDING WITH INSTALLATION
INTRODUCTION
The Z-600 Comfort System™ is a residential and light commercial forced air zone control system that allows a
single HVAC unit to have up to six separate zones. The system can be expanded to as many as 12 zones by
adding 3-zone expansion modules. Intuitive firmware allows the panel to be used with single stage, multi-stage,
heat pump and dual fuel equipment having up to 3 stages of heating and 2 stages of cooling. Standard heat / cool
or heat pump thermostats can be used with the Z-600, along with a choice of two or three-wire zone dampers.
Simple slide switch configuration allows for a wide range of system setup and control options best suited for each
zoning application. Additional features include, fuse protected inputs and outputs, easy-to-read and access wiring
terminals, LED status indication of all system functions, time delay override, adjustable on-board limits, balance
point controls, and selectable ventilation and purge modes. An adjustable upstage timer allows single stage
thermostats to be used with multi-stage equipment. Capacity Control can also stage equipment based on the
number of zones calling. The Z-600 comes in an attractive and rugged 2-piece anodized aluminum enclosure that
provides easy access for wiring, system setup and diagnostics.
WARNING
1. Turn power off to HVAC unit and control panel during installation to prevent serious injury from electrical shock
and/or damage to system.
2. Use extreme care when making duct openings and handling sheet metal to avoid injury.
3. The Z-600 and all components must be installed in a conditioned space where the ambient temperature will not
exceed 150°F.
4. Install all components in a manner that prevents access by children.
CAUTION
1. Installation of this system must be in compliance with all applicable codes.
2. HVAC system must be properly sized and balanced to assure optimum system performance.
3. A bypass damper must be installed to maintain proper system airflow and static pressure.
4. All low voltage wire must be 18 gauge or heavier.
5. All wiring should be color coded and tagged for proper identification.
6. When landing wires to the control panel make sure wires are snug but do not over-tighten screw terminals.
CONTROL PANEL MOUNTING
Mount the zone control panel on a flat, moisture-free surface in a conditioned space that will facilitate easy access
for wiring and system setup.
CONTROL PANEL TRANSFORMER
1. Never use the 24 volt equipment transformer to power the control panel, regardless of it VA rating.
2. Wire a separate 24 VAC transformer of the proper VA to the designated terminals on the zone control panel
marked 24 VAC.
